Compact laser methane detector
The SR-LD 200 lets you detect gas leaks safely and efficiently from a distance. This mobile, hand-held detector identifies methane leaks quickly and accurately from up to 394 ft (120 m) away using TDLAS laser technology, so you can inspect gas pipes and system components even across obstacles such as fences and busy roads. It measures distance and gas concentration simultaneously with automatic plausibility checks — ideal for gas suppliers, biogas plant operators and any hard-to-access inspection scenario where entering a hazardous area is best avoided.
